(a) & (b) These four dams located in Kerala are being operated and maintained by the Government of Tamil Nadu. For preparation of National Register of Large Dams (NRLD), initially technical details and salient features were provided by the Government of Tamil Nadu and accordingly the aforesaid four dams were listed under Tamil Nadu State. Later on after ascertaining that the aforesaid four dams are geographically located in Kerala State, they were brought under Kerala listing and the list of dams in the National Register of Large Dams have been regrouped as per their location within territory of a State. As per decisions of 31st meeting of National Committee on Dam Safety, under Tamil Nadu listing in NRLD, the earlier footnote of “ Periyar Dam is located in Kerala but controlled by Tamil Nadu” got revised to “ Periyar (Mullaperiyar), Parambikulam, Peruvariallam and Tunacadavu dams located in Kerala, but operated and maintained by Government of Tamil Nadu.”
